Exposure to Bovine Leukemia Virus Is Associated
with Breast Cancer: A Case-Control Study

Age, reproductive history, hormones, genetics, and lifestyle are
known risk factors for breast cancer, but the agents that initiate
cellular changes from normal to malignant are not understood.
Bovine leukemia virus (BLV), a common oncogenic virus of cattle,
has been detected in the breast epithelium of humans. The objective
of this study was to determine whether the presence of BLV DNA in
human mammary epithelium is associated with breast cancer.
